Airbus tests the A400M Atlas at maximum load on an uneven runway

One of the keys to a good military tactical transport aircraft is its ability to operate on various types of runways.

These aircraft are designed to operate from unprepared runways, whether dirt, sand (such as beaches), or grass, in order to transport cargo and personnel to all kinds of locations, even without a nearby airport or airbase. The Lockheed C-130 Hercules has demonstrated this capability for many years, and the Airbus A400M Atlas faces the challenge of surpassing it.

This Monday, Airbus announced that it has conducted tests with an A400M Atlas on grass runways. These tests aimed to evaluate the A400M on uneven, slippery, and green terrain, in order to certify its ability to operate on unpaved runways at maximum load for military or civilian missions.

In 2009, EADS announced that the A400M has a maximum takeoff weight of 141 tons, a maximum landing weight of 122 tons, and the capacity to carry up to 37 tons of cargo and 50 tons of internal fuel. It also stated that its minimum tactical takeoff distance (at sea level, with a weight of 120 tons and all four engines operational) is 914 meters, with a tactical landing distance of 822 meters.

In its press release this Monday, Airbus raised the bar for its largest tactical transport aircraft: the A400M, fully loaded at 123 tons, was able to operate on a runway less than 800 meters long and up to 20 meters wide. The test was conducted with the latest prototype of this aircraft, which bears the Spanish civil registration EC-406.

Regarding the A400M's performance under these conditions, Jon Taylor, test pilot for Airbus Defence and Space, noted: "This aircraft's manoeuvrability is impressive. It does not defy physics, but sometimes it seems as if it is trying to."

These tests were conducted in Altengrabow, Germany, in collaboration with the Luftwaffe, the German Air Force. "It aimed to demonstrate the A400M’s ability to operate under extended weight conditions and on softer, vegetation-covered runways. The testing is part of the wider capability enhancement agreement with OCCAR (Organisation Conjointe de Coopération en matière d'Armement), the organisation that manages the programme on behalf of the launch customer nations," Airbus stated.

Today, Airbus Defence and Space released a video showcasing these tests. It's an excellent quality video featuring the European company's staff, mostly Spanish, who collaborated on this process.
